Fire Suppression High-Temperature Exhaust Fan Overview
1. Application: The GYF fire-fighting high-temperature exhaust axial fan meets the GB50045-95 "Code for Fire Prevention Design of High-rise Civil Buildings" and GB50067-97 "Code for Fire Prevention Design of Parking Garages, Repair Garages, and Parking Facilities." It is a new type of energy-saving fire-fighting exhaust fan. This fan can be used for fire and smoke exhaust in various buildings, as well as for exhaust and ventilation in high-rise buildings, general buildings, underground parking garages, mine tunnels, etc. For instance, underground storage areas are typically used for ventilation and air exchange, but can switch to high-volume exhaust when needed.
2. Structural Form: Axial flow blade design; includes GYF-I (single-speed) and GYF-SI (double-speed); two types of fire smoke exhaust fans.
The blade design is of the oblique flow type: featuring two types of fire and smoke exhaust fans, the GYF-II (single-speed) and GYF-S2 (double-speed).
If the user has high noise requirements, a GYF-BX silent fire-exhaust fan can be produced. The fan can also be made in a vertical design, installed on the roof for fire exhaust purposes.
The GYF fire-fighting high-temperature exhaust axial flow fan is composed of five main components: (1) impeller (2) motor (3) internal recirculation fan blade (4) guide vanes, inner tube, and flow guide holes (5) outer casing.
3. Installation and Usage:
1) Vertical, horizontal, and suspended installations are available. The fan base must naturally align with the foundation surface; it is not allowed to敲打下座强行连接. The weight of the piping should not be added to the fan components.
2) Before installation, carefully inspect the impeller and housing for any damage or deformation due to transportation. If any are found, repair them before installation.
3) Check if the connecting bolts are loose, ensure the motor insulation is good, and see if there are any obstructions inside the fan duct that could hinder rotation.
4) After the fan installation, a trial operation must be conducted. Any abnormal rubbing, bumping, or vibration should be eliminated immediately.
